Infinium Wireless was a US mobile virtual network operator that sold service to personal customers on the Sprint, T-Mobile and Verizon networks. Wikipedia lists it as defunct, with an end date of 2017. The sources we read do not say why it closed or which carrier, if any, took its customers.
Infinium Wireless is gone
Infinium Wireless no longer sells service. Wikipedia’s list of US mobile virtual network operators places it in the defunct table with an end date of 2017. It served personal customers on the Sprint, T-Mobile and Verizon networks, using CDMA, GSM, UMTS and LTE technology. No source we read gives an exact shutdown day, a reason, or a buyer.
If you had an Infinium Wireless line
No source names a carrier that took over Infinium Wireless customers. If your old number still works, it now sits with whichever carrier bills you today. Ask that carrier for your account number and transfer PIN before you switch. If the number lapsed when service ended in 2017, it may no longer be recoverable.
How Infinium Wireless ended
- 2017: Service ends, per the End date column in Wikipedia’s defunct US mobile virtual network operator table.
Why Infinium Wireless ended
The sources we read do not say why Infinium Wireless shut down. Wikipedia records only the year, 2017, and leaves the notes column empty. We found no press release, regulatory filing or news coverage of a closure, sale or merger. BestCellular.com reports only what the record shows and does not guess at a cause.
How to find who holds an old number now
- Check an old bill or payment record. It names the company that billed you last.
- Run the number through a carrier lookup tool. It shows the carrier that holds the number today.
- Call that carrier and ask for the account number and transfer PIN.
- Start the port from the new carrier. Never cancel the old line first.
Your right to keep a number
Number portability is federal law, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.
How we verified Infinium Wireless
BestCellular.com tracks active carriers and defunct ones. We keep both, because people still search for brands that no longer exist. Every fact on this page comes from the sources listed below, and we leave a detail out when no source states it. Where sources disagree, this page says so. If you can document a correction, tell us and we will check it against the sources.
Tracked and active are different counts on this site. Infinium Wireless counts in our tracked total, not in our active total, so it does not appear in tools built for live carriers.
